mint heading |
For the 3 trivial programs I tried, using "mint aprogram.exe" is faster than using
"mono aprogram.exe". I wonder if this can be clarified. I would think that mint would
always be slower.

The code of WatchDirectory.cs |
Something must have changed since the book was published, as WatchDirectory produces the error "Delegate can only have one target".
In the original code, "watcher.EnableRaisingEvents = true" should be lower than the next Console.WriteLine command.
Here are my alterations, which seem to work:
public class WatchDirectory {
private static void OnChanged (object sender,
FileSystemEventArgs e) {
Console.WriteLine (e.FullPath + " " + e.ChangeType);
}
private static void OnRenamed (object sender,
RenamedEventArgs e) {
Console.WriteLine(e.FullPath + " Renamed to {1}", e.OldName, e.Name);
}
public static void Main (string[] args)
{
if (args.Length < 1) {
Console.Out.WriteLine ("Usage: <directory path>");
Environment.Exit (1);
}
if(Directory.Exists (args[0]) == false) {
Console.Out.WriteLine (args[0] + " does not exist");
Environment.Exit (2);
}
string path = (string)args[0];
FileSystemWatcher watcher = new FileSystemWatcher(path);
watcher.Filter = "*";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
Console.WriteLine("Enabled watcher on {0}; " +
"hit return to terminate.", path);
watcher.EnableRaisingEvents = true;
Console.ReadLine();
watcher.EnableRaisingEvents = false;
watcher.Changed -= new FileSystemEventHandler(OnChanged);
watcher.Created -= new FileSystemEventHandler(OnChanged);
watcher.Deleted -= new FileSystemEventHandler(OnChanged);
watcher.Renamed -= new RenamedEventHandler(OnRenamed);
Console.WriteLine("done");
}
}
